Just to be clear about this:

This is at least potentially an Actual Problem. It's probably not a
good idea to habitually ignore these. A thing like this happening means
that, at some point:

1. Something created etc/group, and it got inode 29361846 recorded in
the database.
2. Something deleted etc/group, and did NOT record this to the database.
3. Something created etc/group, with inode 29361904.

It's possible that the thing creating etc/group didn't record it to the
database, and something else just referred to it later (like a stat
call), or that this was generated by the request creating the entry.

Either way, it means changes were made to a pseudo-managed hunk of
filesystem without pseudo knowing about it, and that is generally bad.
